From 6154d33de3f15bbd5d5df718103af9c37ba0a768 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Tue, 31 Jan 2017 19:55:33 -0500 Subject: nss-util: silence warning about deprecated RES_USE_INET6 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit src/nss-resolve/nss-resolve.c: In function ‘_nss_resolve_gethostbyname_r’: src/nss-resolve/nss-resolve.c:680:13: warning: RES_USE_INET6 is deprecated NSS_GETHOSTBYNAME_FALLBACKS(resolve); ^~~~~~~~~~~~~~~~~~~~~~~~~ In glibc bz #19582, RES_USE_INET6 was deprecated. This might make sense for clients, but they didn't take into account nss module implementations which *must* continue to support the option. glibc internally defines DEPRECATED_RES_USE_INET6 which can be used without emitting a warning, but it's not exported publicly. Let's do the same, and just copy the definition to our header. --- src/basic/nss-util.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'src/basic') diff --git a/src/basic/nss-util.h b/src/basic/nss-util.h index e7844fff96..9d927a8227 100644 --- a/src/basic/nss-util.h +++ b/src/basic/nss-util.h @@ -27,6 +27,10 @@ #define NSS_SIGNALS_BLOCK SIGALRM,SIGVTALRM,SIGPIPE,SIGCHLD,SIGTSTP,SIGIO,SIGHUP,SIGUSR1,SIGUSR2,SIGPROF,SIGURG,SIGWINCH +#ifndef DEPRECATED_RES_USE_INET6 +# define DEPRECATED_RES_USE_INET6 0x00002000 +#endif + #define NSS_GETHOSTBYNAME_PROTOTYPES(module) \ enum nss_status _nss_##module##_gethostbyname4_r( \ const char *name, \ @@ -92,7 +96,7 @@ enum nss_status _nss_##module##_gethostbyname_r( \ int *errnop, int *h_errnop) { \ enum nss_status ret = NSS_STATUS_NOTFOUND; \ \ - if (_res.options & RES_USE_INET6) \ + if (_res.options & DEPRECATED_RES_USE_INET6) \ ret = _nss_##module##_gethostbyname3_r( \ name, \ AF_INET6, \ -- cgit v1.2.3-54-g00ecf
